. Nevertheless, comparison of the results of body mass obtained during the measurement 2, in 6 of 7 competitors suggested the necessity of reduction of BM2 from 1 to 6.6 kg (from 1.0% to 9.9%, the mean 4.7±3.0%) in order to meet the requirements of weight category limits. Reducing weight of some judokas during
training period was part of a training procedure, however, not all of the contestants, who participated in the study, was qualified for competition. The judoists, whose weight was above weight category limits, INK-128 had still 5 days before the beginning of the contest, which is typical time for rapid weight loss of weight-cyclers . Since the fights are carried out within weight categories, body mass control is incorporated in judoists’ training regimes PCI32765 , but it does not necessarily have an impact on the reduction in motor abilities because the reduction in BM does not exceed 5% . Kubo et al.  suggested that because of the division into the weight categories, the contestants with lower PF should reach higher sport skill level. However, no unequivocal results from studies in this field have been presented so far in the available literature . From the physiological point of view, anaerobic power
and capacity, strength, and aerobic power have been considered the main characteristics to be developed by judo players [24, 28]. Anaerobic capacity is critical to the effectiveness of techniques used in attack and defense. According to Franchini et al.  the anaerobic system provides the short, quick, all-out bursts of maximal power during the match, while the aerobic system contributes to the athlete’s ability to sustain effort for the duration of the combat and to recover during the brief periods of rest or reduced effort. Therefore, Etoposide purchase we observed the post-training changes in the indices, with the most particular development being the time to obtaining peak power (toPP). Contrary to the
placebo group, judo contestants who were supplemented with creatine malate for 6 weeks had significantly higher values of the fatigue index (FI). These results were a natural consequence of faster depletion of muscle phosphagen stores (ATP and CP), mainly in skeletal muscles of type II, caused by generating higher peak power. However, the supplementation with creatine compounds showed no effect on aerobic capacity (VO2max), which was consistent with the observations by [4, 34]. In the study carried out among track and field athletes, mainly sprinters and long distance runners, these authors did not find significant changes in aerobic capacity after the supplementation with creatine malate.A significant increase, however, was found only in sprinters in peak power (PP and RPP) and total work (TW and RTW).
